Many benefits accessible to living things are available solely to cooperative individuals and groups;
2. An individual who is gaining an opportunity by cooperating can often gain even more resources by changing their cooperative behavior to one that is more selfish, either overtly or covertly;
3. When individuals from a cooperative pair or group have repeated interactions, different strategies of cooperation and deception emerge as compared to single interactions;
4. Evolutionary game theory is further complicated by interactions between multiple individuals simultaneously, between individuals of two different species (such as the symbiotic relationship between xxxx), between factions of the same group, and between one group and another (such as law …show more content…

In this scenario, it is always more advantageous, from a personal point of view, to blame the other person. If B stays silent and A defects, person B goes to prison for two years and person A walks free. But if B defects, it is still in A’s best interest to defect, because then he or she would get one year in prison instead of the two they would get if they decided to stay silent. Summarily, defecting always leads to the same or a better outcome, because staying silent can lead to either freedom or two years in prison and defecting can lead to either freedom or one year in prison. Though it would be most advantageous in sum for neither A nor B to defect (thus leading to freedom for both perpetrators), acting in self-interest always leads to the conclusion that defection is the best choice. Therefore, the purely rational choice is to
